Physical anthropology is a branch of anthropology that focuses on the biological and physical aspects of humans. It studies human evolution, genetics, and the variation among different populations. This field examines how humans adapt to their environments and the physical characteristics that define different groups. Researchers in physical anthropology often analyze fossils, skeletal remains, and genetic data to understand human history and development. They may also study primates, such as chimpanzees and gorillas, to gain insights into human behavior and evolution. This discipline helps us understand the biological factors that influence human life and diversity.
